I am having a crack at Backbone and decided to open a jsFiddle to play around.

Unfortunately, I keep getting this error being thrown:

Backbone.Model.extend is not a function

My code:

var Model = Backbone.Model.extend();

I got this piece of code from a Backbone tutorial.

The fiddle.

What have I done wrong?

You need to include underscore.js before backbone.js as in this updated version of your fiddle:

From the fine manual:

Backbone's only hard dependency is Underscore.js.
